Former Solana Executive Tackles DeFi's Latency Issue with a Wall Street-Inspired Solution

Austin Federa, the former head of strategy at the Solana Foundation, left his position in 2024 to address the unfairness he perceived in the crypto trading environment. Eighteen months later, his company, DoubleZero, claims to have a solution. The company aims to remove the competitive advantage of proximity to an exchange's servers by introducing a private fiber network that minimizes latency. This network is designed to create a more equitable environment for traders, even if regulators and traders are not yet demanding it. According to Federa, the issue lies in the conflation of decentralized and distributed systems in DeFi. While DeFi protocols are decentralized due to their open-source code and permissionless validator sets, the physical location of validators can still provide a competitive edge. For instance, traders based in Tokyo have a roughly 200-millisecond advantage over their international counterparts on platforms like Hyperliquid. Federa argues that this is a problem that traditional finance has already addressed. The New York Stock Exchange, for example, has implemented cable-length equalization to ensure that all traders have equal access to its systems. DoubleZero's solution involves timestamping orders and reconstructing a fair sequence of events. The network achieves this by aggregating private bandwidth from operators and routing blockchain data over dedicated links. This allows venues to timestamp orders across global entry points and verify the sequence of events. The challenge is not only to increase speed but also to ensure verifiability. On public internet venues, it is difficult for traders to distinguish between ordinary network congestion and deliberate manipulation. DoubleZero's managed network with deterministic latency makes it possible to prove whether a transaction was delayed due to congestion or other factors. While the laws of physics still apply, and a New York trading desk cannot outrun a competitor in a closer region, the gap in latency is reduced, and more importantly, the variance in latency is minimized. Traders benefit from lower and more predictable latency, which is a key property that high-frequency trading firms value in traditional markets. Federa's broader argument is that the crypto industry is misinterpreting what makes traditional markets fair. Regulators play a role, but they are not the primary drivers of fairness. Instead, it is the exchanges themselves that ensure fairness because their business depends on it. Venues that are perceived as having asymmetric access tend to lose volume to those that are seen as fair. If Federa is correct, the latency issue in DeFi is not waiting on regulatory action but rather on the moment when a major venue decides that fairness is a competitive advantage worth investing in. The next decade will test whether the crypto industry can build distributed systems where the advantage is not based on physical location but on fairness and equality.
